Crawling is more of a process of reading a site. Screens that appear normal to customers may be presented differently to crawlers due to access restrictions or rendering issues.
Just having a visible screen is not enough
The content delivered may vary depending on login, server error, blocking by security systems, or JavaScript execution status. You need to ensure that important body text and internal links are present in the actual response and rendered results.
Make the destination URL clear
For example, if a service detail page is opened only by a menu click event, it may behave differently from a regular link. Check the actual address and connection of the page, and check whether the filter/sort URL structure is constantly increasing. Being able to reach important information is more important than the volume of crawling itself.
Each crawler has a different purpose
We do not treat search crawlers, training crawlers, and tools that visit at your request as the same thing. Classify targets according to operating policies, and check actual request logs and official guidance for each service.
Key takeaways
- Check the response and actual body of the URL.
- Allowing crawling does not guarantee indexing or citations.
- Distinguish between the crawler's service and purpose.
